# Flags for C compiler:
CFLAGS = -g -O0 -Wall -Wextra -std=gnu99
# Explanation of flags:
# * -g: keep debug symbols in the binary (makes it easier to run in gdb)
# * -O0: optimization level 0 (turn off most optimizations)
# * -Wall: Turn on "all" warnings (this name is a complete lie)
# * -Wextra: Turn on even more warnings (because -Wall doesn't include them all)
# * -std=c11: Use the 1999 C standard with GNU extensions

# Flags for C++ compiler:
CXXFLAGS = -g -O0 -Wall -Wextra -std=c++17
# Explanation of flags:
# * -g: keep debug symbols in the binary (makes it easier to run in gdb)
# * -O0: optimization level 0 (turn off most optimizations)
# * -Wall: Turn on "all" warnings (this name is a complete lie)
# * -Wextra: Turn on even more warnings (because -Wall doesn't include them all)
# * -std=c++17: Use the 2017 C++ standard

# Flags for the linker. The compiler translates each .c or .cpp file into a
# compiled "object" file (.o), and the linker takes all the .o files and
